To all whom it may concern:

Be it known that I, SIGMUND GoLoMenK, a citizen of Russia, residing at New York city, (M.anhattan,) county and State of New York, have invented new and useful Improvements in Clock-Movements, of which the following is a specification.

This invention relates to a clock-move ment in which a single mainspring operates the hands, the striking mechanism, and the alarm mechanism in such a way that the various functions thus assumed by the spring may be independently and properly performed.

The invention may also be applied to watchmovements.

Briefly stated, the invention consists in providing a clock with a single spring which by a common train of gears operatively connected to one end of said spring actuates the hands and the striking mechanism, while another set of gears operatively connected to the other end of the spring actuates the alarm. It is evident that the springwill unwind more rapidly during the striking of the clock than during the period in which the hands are moved. As the common train of gears also runs faster while the clock strikes, means are provided which uncou le said train when the clock strikes from the usual connection" with the escapement and from the hands. The latter will thus be at rest while the clock strikes. As soon as the striking is completed the hands and the usual con nection with the escapement are recoupled to the train of gears, which will thus run at normal speed until the next striking.

The construction will be more fully under stood. from the accompanying drawings, in which- Figure 1 is a front view of my improved clock; Fig. 2, a rear view thereof; Fig. 3, a front view of the clock;movement with some of the parts omitted. Figs. 4, 5, and 5 are details of the strike controlling mechanism,

I

The letter a indicates the casing of a clock, the front of which is provided with the dial a and with hands a a a in the usual manner. Within the casing a there is contained the mainspring b, the inner and outer ends of spectively. Of these the first wheel 1) cperates the mechanism for moving the hands and striking the hours, while the second wheel 5 operates the alarm. lantern-wheel 0, fast on a hollow spindle 0,

wheel a to a pinion c ,fast on an arbor 0, carr ing a pinion 0 This pinion drives a wheel ,fast on an arbor d, within tubular spindle c. The arbor (1' turns once every hour and has a reduced end (1, to which the minute-hand a is fastened. Fast on arbor d is a pinion (1 that engages a wheel c, loosely mounted within a bracket a) of frame a. To wheel 6 is secured a pinion 6 which engages a toothed wheel e fast on a tubular shaft a, loosely mounted upon spindle d. Shaft c has a reduced front end a, to which the hour-hand a is secured. Wheel (1, that turns once every hour with aradjoining teeth removed, so that wheel (1 will not be taken along by pinion 0 when the mutilated section (1 arrives op osite the pinion. During this period of rest t e hands (1, a are also at rest, as they are operated by wheel (1 and spindle cl.

Intermediate wheel (1 and pinion d there is loosely fitted upon arbor d a pinion e, that enga es wheel e. Pinion (1 that operates whee c, as above stated, is provided with eleven teeth, while inion e is provided with twelve teeth. As oth pinions d e engage the same wheel e, a differential movement is thus im arted to pinions d ethat is, inione wil fall back for exactly one toot at each complete rotation of pinion d and wheel d. This differential movement is used for regulating the number of strokes, so that they conform to the different hours in the fol- Wheel b engages a bor d, is mutilated, as at d by having two' which are secured to toothed wheels I) b rethat in turn transmits motion by a toothed which is free to turn IIO lowing manner: To pinion e is secured a snail or cam disk e provided with twelve ste s approxim'ately'radial edge e".

v curved lever e will fall back for exactly one that successively decrease in radius. T e first step e of the lar est radius is connected to the last step e of t e smallest radius by an The steps'are adapted to be enga ed by the bent end e" of a his lever is pivoted to wheel d at e and is pressed toward the snail by a spring e The other end of lever c has a pin e", which is received by a radial slot of a toothed sector f.- The latter turnsloose yon arbor d and is inter osed betweenwheel d and disk 6 to that of the sector, and the pitch of the teeth on both is alike, so that pinion c is adapted to engage wheel (I and sector f. As thus far described, it will be seen that at each 'complete rotation of wheel (1 to the arbor d of which the minute-hand is secured, pinion e twelfth of a complete rotation. Cam-disk 6, being secured to pinion 8, will also be retarded for one-twelfth of a rotation-ql. e.,-'for the length of one step. This rotation of snail e in relation to Wheel d is utilized for setting sector f, that controls the number of strokes of the hammer. The relative position of wheel (1, sector f, and lever e is such that when lever e engages the ste e of the largest diameter one tooth of-w eel d willbe exposed between the end of sector and a pin 01, secured towheel d, Fi 5. T 's position of sector f relative to muti ated wheel d allows engage the smallest step e.

the gon to strike once-to announce one oclock time. he mechanism for said sounding of the gong-will be hereinafter described.

During the hour succeeding the striking the hook e will ride along step e until the hook arrives opposite the adjoiningistep e. The parts are so adjusted that hoo e arrives o osite the succeeding step e before tl ie ll hour has elapsed. Sprin a by pressing upon lever a, will slight ti t the latter on pivot e. This tilting of ever e results in a partial rotation of sector f in relation to wheel- As will be readily understood from Fig.

I 5, pin e of lever e will be slightly swung up as soon as hook leaves step e and engages step e. The slight upward movement of pin e will by the engagement with slot f of sectorfrotate the latter for. the-length'of exactly one tooth. In this way two teeth will become exposed or be-left uncovered between the end of the sector and pin d. It will thus be seen that as soon as hook (2 passes from one-step to another (which movement takes place once during every hour) the number of teeth exposed between sector f and pin 6" will be increased by one tooth. Aftertwelve hours have elapsed hook e will gradually pass from the position shown'in'Fig. 5' to the position shown in Fig. 4, when saidhook will twelve teeth are .left uncovered lbetween sec- The ra 'us of wheel d is equal tooth-1.12., one-' ln'thisposition tor f and pin d, so that the gong will be sounded twelve times in manner hereinafterdescribed.

For the sake of greater clearness it may be stated that'the position of snail e in relation to wheel (1 determines the position of sector f upon wheel d, while sector f, in connection with wheel d, controls the number of strokes of the hammer.

The striking operation takes lace as soon as the mutilated section (1 of w eel d arrives oppositeinionc- As sector f is so arra'n ed a ove w eel d-that is, can only pla etween the two end positions shown in Figs. 4 1 and 5it willbe seen that the mutilated section (1 of wheel d is always covered by sector When said mutilated section of wheel d and the sector f arrive op osite pinion 0, wheel d will be arrested, whi e sector f 'will alone be rotated in the direction of the arrow, Fig. 4, untilit bears against stop-pin d, and thus takes wheel (1 along. After a sli ht rotation imparted to wheel d by sector f t e tooth adjoining the mutilated section of wheel d will engage pinion 0 so that the latter will now again turn the wheel for one comfplete rotation, corresponding to the lapse 0 one hour, when the mutilated section will again arrive opposite pinion c to cause the hammer to strike the next hour. that during said rotation of wheel d hook e" has passed from one step of snail e to the next step, so as to change the position of sectorjg' relative to wheel d.

s has already been stated, wheel (1 and sector f control the striking mechanism in such a manner that the hammer strikes once for every dental movement of sector f upon wheel d. The means for effecting this result are as follows: An axially-movable shaft 9 is rotated from arbor c by wheel c and lantern-wheel g. Spindle g carries a wheel g,

It will be observed that is adapted to engage a pinion g operatg", which is of the same size as the teeth of wheel g and which is in alinement with one of such teeth. This tooth intermittently engages pinion 9 when wheel 9 is rotating, but without then performing any work. After shaft 9 has been shifted to the right, Fig. 6, in manner hereinafter descrihed-wheelg is out of enga ement with pinion 9, while the tooth g. of ger g is stil adapted to engage pinion g and to permit intermittent rapid consecutive rotations of shaft- 9 whenever the parts g g"- are thrown out of gear. The parts are so set that shaft 9 is shifted laterally, while tooth g of finger g is in enga ement with pinion 9". As soon as during t e continuing rot'ationof wheel 9' and finger g the IIC 'tarded by beinga latter clears pinion g the tension of s ring I) will cause shaft 9, together with whee g and finger g, to make a rapid rotation until tooth g rengages inion g. This rapid movement requires ut a very short time, so that the escapement G, owing to its momentum, is still in motion when tooth g reengages pinion' g after having performed sa'idrapid rotation. The'tooth g and consequentl shaft g, is now retarded while contacting with the rotating pinion g of the escapernent, while after clearing the same it will make an additional rapid rotation until it is again rethrown into engagement with pinion g ach rapid rotation of shaft 9 causes, b parts 9 c", a corresponding rapid and partia rotation of arbor c and inion 0 The parts arev so proportioned t at each rapid rotation .of shaft gwill advance pinion c"' orthe length of one tooth, while they are so timed that said rapid rotation takes place after the hands have stopped- 5. e., after the mutilated section d of wheel d has arrived opposite pinion c. In this osition of the parts sector f only, and not w eel d, is in engagement with inion 0 It will thus be readily understood that each complete rapid rotation of shaft 9 will advance sector f for one tooth when pinion c is advanced for one tooth. The number of consecutive ra id rotations which shaft 9 is allowed to ma e depends upon the position of sector f, which in turn depends upon the position of snail e*. If, for instance, twelve teeth are ex o'sed between sector f and pin (1, Fig. 4, s aft 9 will be allowed to make twelve rapid rotations. After the twelfth rotation sector f contacts with in d, so that the sector will take along whee d to restart the hands.

Each ra id rotation of shaft causes one stroke of t e hammer in the folfowing manner: Upon shaft g. is mounted a crank-pin g, which when shaft gisf shifted to the ri ht, Fig.

' 6, is thrown across the path of a ever h,

mounted by pin h upon a rock-shaft h. The

rock-shaft h is influenced b a spring h and carries the hammer ht ach rotation of shaft g when the latter is shifted will therefore,-by lever h and shaft h, swing the hammerh to execute one stroke of the gong. It

will thus be seen that the number of teeth of wheel d which are exposed between sector f and pin dfldetermines the number of'ra id rotations of, shaft g and that each of suc rotations causes one stroke of the. hammer.

To operate shaft g, I employ a three-arm lever i Vi pivoted at 1?. Arm '5. of such lever is engaged by the arm 9'" of a shippingivoted' at '1' and operated in manner lever 7,

.hereina ter described. Arms 'i' i are provided at their free ends with plates 0') i that rest against the left and right ends of shaft 9,

respectively. When arm 1" israised, it will by hearing ageinstarmi of lever 'i i "i turn saidv e right -t. e. from the posit on lever to .t

shown in Fig. 6 to that shown inFig. 6. Plate '1'," of lever-arm i will durin this movement take spindle g along and shi t it to the right, Fig. 6, in order to disengage wheels g g and to bring crank g into t e path of hammerlever h, as hereinabove referred to. End

plate i is influenced by a s ring i, which tends to turn lever i i t to t e left. After the shipping-lever 1' has been release. in manner hereinafter described spring i will turn lever i i i to the left. Durin this movement shaft 9 will also be shifte to the left, Fig. 6, by the enga ement of the right end of shaft g with end p ate *6", so as to renga e parts 9 g and to withdraw crank g from tl ae ath of lever h. The turning movement of ever i i i also causes arm '5 to be depressed and to thereby return lever to its normal position.

The shipping-lever j is operated in the following manner: To wheel (1 is pivoted, by projecting'pin k, a bent lever I, having pin k nearits angle. The pin k is adapted to engage a finger pivoted tolever j at 1' and normally held off the same by spring The arts areso. positioned that when t e *muti ated'section d of wheel (1 approaches pinion a pin 76 will bear upon finger 1' and thereby swing the'latter toward lever j and compress s ring j. During this operation lever is he (1' against displacement b a pair of pins d projecting from wheel (1 an adapted to successively engage an arched collar j of lever j. Pins d v are so positioned that when the mutilated section of wheel (1 is opposite pinion c the pins d will clear collar 1' and permit the spring jto rapidly tilt lever 1', so as to raise arm i, and consequently shift shaft gin manner hereinabove described. In this depressed position of lever j a transverse groove 1' of the latter will be projected over pin k, and thereby lock wheel d against rotation. In this way any rotation of wheel (1 during the movementof sectorf is prevented. When the sector f is about to complete its independent movement, a,beveled arm f 2 of the same will bear against free end it of lever is and tilt the same, so that pin k is disengaged from finger The lever'j being thus released will, together with. shaft g, be returned to its normal positionby spring 11 to ITO arrest the striking mechanism and restart the hands.

To cause the strikingmecnamsm to be released only when the crank g is in the proper position with relation to lever h for striking said lever during its rotation, there is fulc'rumed" to the frame a at 1 an elbow-lever Z.

One arm of this lever terminates in an ellip-- 'tical eye I, which is engaged by crank 9 so that in this way the crank im arts an oscillating movement to the lever The second arm of this lever is notched, asat l, to engage a pin 1" of lever Thus when the crank g swings eye I? downward notch Z 1o manner.

pinion 0 lease pin 7'' to liberate lever j, Fig. 7, while when e e Z is swung up by crank g lever j will be ocked.

' The operation of the above described 5 mechanism for moving the hands and striking the hours is as follows: Assuming the parts to be in a position shortly prior to that shown in Fig. 4, wheel (1 is slowly rotated by pinion to operate the hands in the usual When it is exactly twelve oclock, mutilated section (1 of wheel (I has arrived opposite pinion 0 so that wheel d, and consequently the hands, will notmove until the twelve strokes have been given by. the ham- Before the parts assumed the position shown in Fig. 4 pin W has ressed finger j toward lever j, the latter being held against displacement by pins (1 As soon as the mutilated section d has arrived opposite 2o pinion c the lower pin (i Fig. 7, will have cleared'collar of lever Spring will therefore rapidly turn the lever to raise its arm 1' and thereby turn. lever a i i to the right, so as to shift shaft 9 correspondingly,

In this way parts 9 g are disengaged and shaft 9 is allowed to make twelve consecutive rapid rotations, as twelve teeth are exposed between sector f and pin cl. At each rotation of shaft 9 the gong is sounded 0 once by the engagement of crank g and lever 72/ and the sector f is advanced for the distance of one tooth, wheel (1 being arrested b the engagement of the parts 7c. The gra ual advancement of'sector f will gradually 3 5 turn lever e on its pivot e by the engagement of slot f and pin e. At the twelfth stroke lever e will have assumed the position shown in Fig. 5*. During the twelfth or last stroke of the clock beveled arm 2 of sector f 4o bears against the free end k 0 'lever 7c and tilts the same, so that pin k is disengaged from finger 1 The lever y' being thus released will also release lever i 1' i Spring '5 will thus be permitted to turn said lever 'i a i 5 to the left in order to,reeng'age parts g g and to bring crank g out of the path of lever h. The rotation of lever 01 'i i will by the engagement ofparts i j swing leverq' into its normal position, Fig.8. After the last 50 stroke of the clock sector f engages pin dtof wheel (1, and as parts g g are rengaged b the shifting of shaft 9 to the left sector f will be slowly rotated, Whereb it takes wheel (1 along, so that the-teeth 0 wheel d rengage In this way the hands are restarted immediately after the strikingis over. tectorf and wheel (1 will now 'ointly enga e pinion 0 so that the latter will now turn t e sector, as well as the wheel.- After the last 6 0 tooth of sector f has cleared-pinion 0 spring pinion-c5, and the operation just descri ed is repeated; but as there is now only one tooth exposed between sector 7 and pin (1, Fig. 5,

the gong will be sounded only once, thus indicating the hour of one oclock. As the snail e is retarded at each rotation of wheel (1 for one step the lever e by engaging a new step will add a tooth to the number of teeth previously exposed between sector f and pin at until the hour of twelve oclock, when the lever e is lifted from the twelve-oclock step e to the one-oclock ste e by the engagement of in e of lever c with slot f of sector The a arm is sounded by the same hammer b which sounds the hours. It is operated by the usual notch disk m, which releases a spring-lever m, the upper bent end of which is thus drawn out of the path of lever h, and thus permits the vibration of shaft h, and conse uently of hammer h. The alarm is arreste b a pin b of ratchetwheel I), which is use in winding up the sprin Pin b upon the full rotation of whee 12 contacts witha pin 'n of a ratchetwheel n, loosely mounted on spindle b of wheel b Thus wheel n is taken along by wheel I) and will by hearing against a nose 0' of a lever 0, fulcrumed at 0*, swing said lever upward. Lever 0 will thus tilt a lever 19 on fulcrum p, and thereby project a stop 11 of said lever over a finger g of s indle g, so that the latter is arrested. Spind e g receives motion from wheel I) by lantern-Wheel r, shaft r, wheel 1", and pinion g. It carries the wheel that vibrates rock-shaft h by double paw k in the usual manner.

It will be seen that in my improved clockmovement. the hands, striking mechanism, and alarm are allactuated by one and the same mainspring and that the hands and the striking mechanism are operated by a common train of gearing in such a manner that the hands are arrested while. the hammer is the construction described be prevented from going too fast while it strikes, and thellsfifiring 18 thereby permitted to its dual functions.
